BACKGROUND OF INVENTION

[0001] 1. Field of Invention

[0002] The present invention is related to a nail dryer.

[0003] 2. Related Prior Art

[0004] A lot of ladies like to wear nail polish on their nails and more particularly finger nails for aesthetic reasons. However, it takes a long time for the nail polish to dry in the air naturally. Therefore, a lady has to waste a lot of time waiting for the nail polish on her nails to dry off. To avoid such waste of time, some nail dryers have been devised to expedite drying of the nail polish on nails.

[0005] Sometimes, ladies dry nail polish on her nails with a hair dryer. Use of the hair dryer to dry the nail polish requires some skills. If the hair dryer is positioned too far from the nail polish, a small portion of hot air sent from the hair dryer can contribute to the drying of the nail polish. If the hair dryer is positioned too close to the nail polish, the nail polish will be wrinkled by strong air sent from the hair dryer.

[0006] For example, Taiwanese Patent Publication No. 209346 discloses a conventional nail dryer that includes a handle extending from a shell. A light source that can emit ultra-violet light is installed in the shell. The shell defines a slot through which ultra-violet light emitted from the light source can spray. After wearing nail polish on her finger nails, a lady can hold the handle with her hand so that the ultra-violet light shines on her finger nails in order to cure the nail polish. This conventional nail dryer however may cause a problem on human health, i.e., the ultra-violet light may hurt a user's skin.

[0007] The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
